Vedclass · Answer

(B) In a soda-acid fire extinguisher,the two main components are a solution of sodium bicarbonate $(NaHCO_3)$ and sulfuric acid $(H_2SO_4)$.When the extinguisher is activated,the acid reacts with the bicarbonate to produce carbon dioxide gas $(CO_2)$,which helps in extinguishing the fire.The chemical reaction is: $2NaHCO_3 + H_2SO_4 \rightarrow Na_2SO_4 + 2H_2O + 2CO_2 \uparrow$.
